Question

Закончите уравнения следующих реакций. Na2CO3+HCl-> NaOH+HCl-> Fe(OH)3+HNO3-> Mg+H2SO4->

Answer 1

Na2CO3+2HCl->  2NaCl + H₂O + CO₂
NaOH+HCl-> NaCl + H₂O
Fe(OH)3+3HNO3-> Fe(NO₃)₃ + 3H₂O
Mg+H2SO4-> MgSO₄ + H₂

Answer 2

Na2CO3 + HCl -> NaOH + HCl

The reaction between sodium carbonate (Na2CO3) and hydrochloric acid (HCl) can be represented as follows:

Na2CO3 + 2HCl -> 2NaCl + H2O + CO2

In this reaction, sodium carbonate reacts with hydrochloric acid to produce sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2).

NaOH + HCl -> Fe(OH)3 + HNO3

The reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) does not directly produce iron(III) hydroxide (Fe(OH)3) and nitric acid (HNO3). It seems there might be a mistake in the given equation.

Please provide the correct equation, and I'll be happy to help you with it.

Fe(OH)3 + HNO3 -> Mg + H2SO4

The reaction between iron(III) hydroxide (Fe(OH)3) and nitric acid (HNO3) does not directly produce magnesium (Mg) and sulfuric acid (H2SO4). It seems there might be a mistake in the given equation.

Please provide the correct equation, and I'll be happy to help you with it.

Mg + H2SO4 -> ?

The reaction between magnesium (Mg) and sulfuric acid (H2SO4) can be represented as follows:

Mg + H2SO4 -> MgSO4 + H2

In this reaction, magnesium reacts with sulfuric acid to produce magnesium sulfate (MgSO4) and hydrogen gas (H2).
